This invention relates to manifolding books and the like using carbonsheets as a means to provide one or morecopies of an original at oneWriting. Two princi al forms of such books are at present emp oyed, oneusing a single carbon sheet which must be handled andwhich is expectedto make a maximum of fifty copies. The principal objections to thesebooks are that the carbon leaf must be handled, and that the copiesobtained are not uniformly legible. The other form of book employs acoating of carbon on the back of each original sheet. The principalobjections to this form are that the clerk and in many cases thecustomer each have to handle a carbon coated sheet, and such sheetscannotbe enclosed with easily soiled goods.

/ In the present invention my object is to devise a form of book (a) inwhich the necessity an of handlii'lg a carbon sheet each time the bookis used is avoided, (b) which may be so used, that at no time is acarbonized surface exposed for contact Willh the users hands, (0) whichwill enable duplicates of the originals an of uniform legibility to beproduced, (01) which will provide in bound form, numerical- 1y arranged,copies of all entries made, so that any subsequent alterations made inoriginal sheets may be readily detected, (e) and so which, as aplurality ofcarbon sheets are employed, in the book, the used carbonsheets are retained in the book in such a manner that they require nohandling and are protected from damage or disfigurement of theimpression made thereon 'durin use.

Further objects will ereinafter appear from the detailed description andillustration of the invention.

\ Briefly my construction is as follows: The book is made up of aplurality of units, bound in together, each comprising a duplicatesheet, a carbonsheet, and an original sheet united along one edge to theduplicatesheet and folded over the carbon sheet. 3

The book is provided witha'cover having a stop sheet connected with theback adapted to be folded into thebook. The originals and duplicates,and preferably the carbon sheets, are consecutivel numbered from theback to the front of the 00k, which is thus used from the back to thefront, the stop sheet being interposed between a unit to be used andover nal, and sometimes the duplicate, is torn out,

the stop sheet is hinged out of the book and then swung back into placeover the used carbon sheet, or carbon sheet and duplicate, remaining inthe book.

The invention is hereinafter more fully described, and is illustrated inthe accompanying drawings in which Fig. 1 is a perspective view of oneunit of the book comprising an original sheet, adupli cate sheet and acarbon sheet;

Fig. 2 a perspective view of a book constructed in accordance with myinvention as it appears when ready for the making of an entry on anoriginal sheet;

Fig. 3 a similar view showing the original and duplicate in position tobe torn ofi Fig. 4 a similar View, after the original and duplicate havebeen torn oflflshowing the stop sheet lifted to allow the carbon sheetto drop; and r Fig. 5 a similar View showing the book with the originaland duplicate removed and the stop sheet turned in over the carbon leafready for the drawing down of a new unit.

In the drawings like numerals of reference indicate corresponding partsin the different figures.

Referring particularly to Fig. 1 of the drawings, it will'be seen thateach manifolding unit comprises a duplicate sheet 1 provided with a longstub 2, a carbon sheet- 3 superimposed thereon, and also provided with along stub 5, and an original sheet 4 united to the free end of theduplicate sheet and normally overlying the carbon sheet.

The stub of the carbon sheet is non-carbonized, as shown, whichfacilitates the consecutive numbering of these sheets and gives a cleantop for handling, if necessary, and lessens the liability, if the carbonsheet be handled, of defacing the record thereon. The opposite end ofthe carbon sheet is also formed with a non-carbonized margin 6 whichsimilarly facilitates handling if at any time handling be necessary.

By means of the stubs 2 and 5 a plurality of the manifolding units arebound together to form a book, as shown in Figs. 2 to 5 of the drawings.

'The book is provided with a cover, which includes, at least, a back 7,and a portion 8 bound to the stub of the book. It will usually alsoinclude a front 9. A stop sheet 10 is connected, preferably integrally,with the free end of the back 7 ,so that it may be used as hereinafterdescribed. The originals and duplicates will be printed, as usual,according to the requirements of the purchaser, and will be nun'iberedconsecutively from the back to the front of the book. Correspondingnumbers will usually appear on the carbon sheets, preferably by beingimprinted on the stubs Bhereinbefore referred to. The stop sheet alsoacts as a record sheet upon which a summary of the sales may be entered.Perforations or other lines of weakness will usually be employed tofacilitate the separation of the originals from the duplicates andseparation of the duplicates from-their stubs.

As a separate carbon sheet is provided for each manifolding unit, I findit desirable, in order to avoid making the book too bulky, to use forthe carbon sheets a very thin, cheap paper having a very light coatingof carbon applied to the same. Such carbon sheets possess the furtheradvantage that, owing to their fragile nature itis impossible to makealterations therein without detection. These sheets thus serve as apermanent reliable record of all entries made in the book.

The mode of operation will i .ually be substantially as follows. Themanifolding units are thrown back over the front cover, as shown in Fig.2. The long stubs employed permit this to be done so that the book willlie flat on its supporting surface. The stop sheet 10, then rests on theback 7. The first manifolding unit or set of leaves (1, 3, 4), Which isuppermost when the book is so opened, is then pulled towards the userand dropped on the stop sheet 10'. A record or memorandum is then madeon the original sheet from which, through the medium of the carbon sheet3, a copy is made on the duplicate sheet 1. A legible impression is alsoformed on the carbon sheet 3. The original may be then torn from theduplicate, or the original and duplicate torn together from the stub andsubsequently separated. The removal of the sheets 1 and 4 leaves thecarbon sheet resting on the stop sheet 10. The stop sheet 10 is thenlifted (see Fig. 4), allowing the carbon sheet 3 to drop down on theback 7 This operation, it will be noted, does not require any handlingof the carbon sheet. The stop sheet is then allowed to drop on thecarbon sheet and the book is then in position for entering the record ofthe sale on the printed form on the stop sheet, and leaves the book, ifsubsequently closed, in shape for convenient opening at the right placefor making the next record, which involves merely a. repetition of thesteps just described.

If the duplicates are left in the book the non-carbonized margin of thecarbon sheet facilitates the raising of the carbon sheet to obtainaccess to an underlying duplicate without soiling the fingers.

In case the record made, on a given unit, has not been completed or itis required to be referred to later, the whole unit may be droppedbeneath the stop sheet and lifted out for completion or examination atany subsequent time without touching any carbon surface. The record,when the unit is so held under the stop sheet, is kept safe from anyaccidental defacement.

During all these operations, it will be seen that the carbonizedsurfaces are at no time exposed and at no time is it necessary for theuser to handle the carbonized surfaces.

From the above description it will be seen that the invention provides asimple and practicable counter check book which will satisfactorilyattain the objects of my invention asset out in this specification.

What I claim as my invention is:

A manifolding book comprising a back, a plurality of manifolding units,each unit comprising a carbon sheet and a detachable duplicate sheetbound to the back and an original sheet united to the duplicate sheetalong one edge with its opposite edge free and folded over the carbonsheet, and a stop sheet united to the back and foldable over the usedcarbon sheets and between the same and the next duplicate sheet andprotecting the record on the used carbon sheets aganist mutilation Whilemaking subsequent entries.
